This invention relates to sponge-cups andv more particularlyy tosponge-cups usedin oiiicesl and banks for the purpose of facilitatingthev handling or counting of paper sheets or paper money.

@ne ofthe main objects vof the invention is to provide a sponge-cup inwhich the overflowing of the water out of the cups, as often occurs incups as used at the present, is eliminated. such an improved cup of verycompact and reduced dimensions in relation to the size of the spongeused. A further object/is to provide a cup of cheap manufacture in whichall parts are'so shaped and proportionedl as to enable the cup to vbeformed. in a mold of simple construction. Further objectsor advantageswill appear from the following le scription and from the drawings whichform part of this application forjL'etters Patent. In the drawings l? lis a top plan View of the device constructed in accordance with myinvention. Fig. 2 is a sectional'elevation taken o line 2 2 Fig. l. c .lA'

rlhe device whichmay be madeof glass, porcelain, or any other moldableandwater proof material, is preferably made circular and consists of abody 1 havingv a circular depression orV cup 2. of suitable size anddepth; the wall 3 formed by this depression has its top so shaped astoform two concentric edges or rims d and 5, separated by the groove 6.The bottom of the latter is not level but is formed so as to present twohigh points and two low points so disposed that the'high and low pointswill be respectively diametrically opposite eachother. ln the inner edge5,1and at'points corresponding to the lowest' levels of groove 6 thecuts or slots 7 with sloping bottoni 8 are provided for the piirposeofdraining the water Another object is to provide d Specification ofLetters Patent. fV Patented J V17.9212. i

in thegroove,backgintothe cupi4 2,'wherein .the sponge 9 is loca-ted. Af Y 1W hen it is desired to use the device, the

spongel is saturated with-water until the latter reaches approximatelythe'bottom of the drain slots 7. As will be experienced, 1 the pressureexerted bythe linger'sfto be moist'ened, willcompress the spongeV sufli-'ciently' llgforce a certainamount ofthe water retained in the upperpart yof the sponge to oo'ze out and over-flow outside of the firstledge. Inthe ordinary sponge-cups, as now f generally used,thisnaturallyvresults in the f waterl spilling over the border and,creating unsightly poolsiiponthe desk, or perhaps even damagingimportant documents which Vmight happen lto be in thefvicinityof the Ysponge-cup. I incidentally, these all too frequent occurrencesy areoftenv the cause of much valuable time. and'oiiice material being wastedin cleaning and repairing the damage done by them.` In my" inventionthis. danger due to the overflow of water isfdone 'away with by the useofthe outeredge which,

for greater precaution,- is made' somewhat.v

`higher than the inner edge.- The expressionV of water from` the spongebythe lingers of course notprevented yin my device butr water beingdrained by the inclined Referring to the drawings it will be seenthatthe walls, edges andcuts are so 'tapered as to allow theci'ipsbeingformed and drawn outof the mold directly,'*without requiring`the settingv and removal'of loose pieces or Y collapsible-mandrels.`This` labor saving fea- Y ture of myf invention 1s of great importancef especially lwhenconcerning articles which.

arey to be producedy in great quantities. Furthermore, the width'ofthedraining groove 'may be' made relativelysmall without im-V pairingitscapacity for conducting the over-i flowing waiter, thereby obtaininga very compact device requiring but little space on va desk Vor counter.

'F rom the foregoing description taken in connection with theaccompanying draw rings it will be apparentthat l :provide a sponge cup'possessing valuable and practi-` cal advantages v)over theV -kinds used.at present, and of very cheap and simplel manufacture.y As willrbefeasilyV understood there v maybe made slight Vchanges in they design ofLthe cup, such as makingV it polygonal instead of circular, and I do notwish to limit myself to the i''orin described above except l as 'setforth in the claims hereuntov appended.

What I claim as new and desireto secure Y by Letters Patent is 1. As anarticle of lmanufacture7 a flat tween possessing a plurality of high andlow l 3. As an article of manufacture', a sponge level points; the levelpoints of equal depth being diametricallyopposite.

cup having two concentric rims at Vthe top of-its side; theiiiner rimbeing of lesser height than the outer rim; a drainage groovetherebetween possessing a plurality of high and low levelvpoints, thelevel points of equal.

depth being diametrically opposite, and

apertures provided in the inner rim atpoiuts 25 corresponding to the lowlevel points oaf said rgroove, substantially as described, i ,Y
